I think that BItcoin mining does have some strong centralizing pressures: latency in new block announcements and variance both favor larger miners. So a single miner gaining 51% or more of the hashrate is a real concern in my mind.

I'm curious to hear an elaboration of this. I'm not well-versed in game theory.

The part of Bitcoin you *have* to trust

To trust means to accept something you can't verify by logic. Game theory tells me that miners are better off making bitcoin network stronger rather than joining forces in a 51% attack to kill it. No government can change that incentive.
